Hi,
My overlay has displacement from VirtualEarthOverlay when resize the browser, but WorldMapKitWmsWebOverlay works good.
I create a little sample to show this problem. When resize the browser, it will call my function to change the css class to make the map's size change. If I use VE as background, my arrow overlay will not match it, but if i use WorldMapKitWmsWebOverlay as background, my arrow already match the roads of it, not matter how you change the size of browser.
